Evidence for a change of slope in large-t elastic proton-proton scattering at square root s=53 GeV
/ De Kerret, H ; Aubert, Jean-Jacques ; Bartl, Walter ; Brandt, A ; Broll, C ; Büsser, F W ; Coignet, G ; Dibon, Heinz ; Eichinger, H ; Favier, Jean et al.
New experimental results are presented on proton-proton elastic scattering in the range of momentum transfer 4 GeV/sup 2/<-t<10 GeV /sup 2/ at the centre-of-mass energy of square root s=53 GeV. The data have been obtained using the split-field magnet detector at the CERN Intersecting Storage Rings. [...]

A study of the charge-exchange reaction $pp \to n\Delta^{++} (1232)$ at ISR energies
/ De Kerret, H (CERN) ; Aubert, Jean-Jacques (Annecy, LAPP) ; Bartl, Walter (Vienna, OAW) ; Brandt, A (Hamburg U., Inst. Exp. Phys. II) ; Broll, C (Annecy, LAPP) ; Coignet, G (Annecy, LAPP) ; Dibon, Heinz (Hamburg U., Inst. Exp. Phys. II) ; Eichinger, H (Vienna, OAW) ; Favier, Jean (Annecy, LAPP) ; Flügge, G (Hamburg U., Inst. Exp. Phys. II) et al.
A study is reported of the charge-exchange reaction pp to n Delta /sup ++/(1232) at the CERN intersecting storage rings (ISR) in the energy range square root s=23 to 53 GeV. From the analysis of the energy dependence of the total cross-section, of the differential cross- section d sigma /dt and of the decay angular distributions evidence is found that pion exchange is dominant up to square root s=23 GeV and that ( rho +A/sub 2/) exchange dominates the reaction for square root s>or=30 GeV, as described by simple Regge-pole models.

Observation of high mass mu /sup +/ mu /sup -/ pairs at the ISR
/ Nagy, E ; Brandt, A ; Broll, C ; Coignet, G ; Dibon, Heinz ; Eichinger, H ; Favier, Jean ; Flügge, G ; Gottfried, Christian ; Neuhofer, G et al.
Observation of 16 mu /sup +/ mu /sup -/ pairs of invariant mass greater than 2.7 GeV/c/sup 2/ in the reaction pp to mu /sup +/ mu /sup -/+anything at square root s=52 GeV at the CERN Intersecting Storage Rings (ISR) is reported. These events can be interpreted as originating from J(3.1) decay into mu /sup +/ mu /sup -/. [...]

Decay angular distributions in diffractive one-pion production at ISR energy
/ De Kerret, H (CERN) ; Nagy, E (CERN) ; Regler, Meinhard (CERN) ; Schmidt-Parzefall, W (CERN) ; Schubert, Klaus R (CERN) ; Winter, Klaus (CERN) ; Brandt, A (Hamburg U.) ; Dibon, Heinz (Hamburg U.) ; Flügge, G (Hamburg U.) ; Niebergall, F (Hamburg U.) et al.
New experimental results are reported on decay angular distributions in diffractive dissociation of protons into (n pi /sup +/) in proton- proton collisions at a centre-of-mass energy of square root s=45 GeV. There is strong evidence for two distinct components of diffraction dissociation which have different decay angular distributions in the Gottfried-Jackson frame; the resonant and the non-resonant component with (n pi /sup +/) invariant mass in the interval 1.6<m<1.7 GeV are separated by their different t dependence.

A measurement of the cross section of the reaction $pp \rightarrow n\Delta^{++} (1232)$ at ISR energies

A measurement of the cross section of the charge-exchange reaction pp to Delta /sup ++/(1232)n at square root s=23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependences continues to follow a power law p/sub lab//sup -n/ with n=1.94+or-0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.
